I hear ya brother
I was a very big telewest fan, but even I am getting to the end of my tether.
What hacked me off was the Indian call centre who's job seems to be to try to place the blame on you! they must go through a check list headed 'pass the buck blame the customer', the chap I spoke to got me to type Netstat -a to see what was connected to my PC, I had 6 established TCP connections, he didn't have a clue what they were, all he said was 'your infected with spyware you have to scan your computer'.
After I got off the phone to him i shut down MSN and IE and all the established TCP links were gone, he didn't want to know that it was a clean install of Windows XP, from the day before or that I was running zone Alarm and Nod32, no basically I was losing half my Download speed to spyware.
I don't want to go but I'm not paying £35 for a 5mb service.
